Nova Scotia prepares for blue-green algae as the summer season begins

Blue algae blooms are making their presence known in the Maritimes as summer approaches.
It may not have been beach weather in the Halifax area Wednesday, but as the summer approaches it won't be long until beaches are full.
'Around this time of year, we're working with our colleagues in recreation, making sure all of our protocols are up to date, and that any changes that need to be made have been approved,' said Halifax Regional Municipality Environment Manager Emma Wattie.
Supervised beaches in Halifax officially open for the season July 1, which is when water quality testing begins.
'Bacteria likes it warm. They like it sunny, much like us, but they want more shallow water typically,' said Wattie.
Both the Nova Scotia and New Brunswick governments are warning about the risk of blue-green algae as temperatures rise.
It can look like fine grass clippings in the water, spilled paint, pea soup or sometimes like a thick scum on the surface.
Consuming or swimming in water with blue-green algae can cause skin, eye and throat irritation in humans but it can be much worse for dogs.
'These toxins are extremely potent, so even a small volume can be lethal,' said Dr. Dan Maguire, a veterinarian at PetFocus Veterinary Hospital Bedford South.
Maguire said if you think your pet may have consumed contaminated water, you should get them treatment right away.
'This can be harmful to both the liver and the nervous system,' he said. 'Symptoms can appear from minutes to hours, and we're looking for things like vomiting, diarrhea, weakness.'
Wattie said blue-green algae is happening more frequently and in larger blooms but there wasn't any more in the Halifax area last year than in year's past.
'When a beach or a lake has a blue-green algae bloom, it's more likely for that bloom to come back year to year, so we are seeing it in areas like Cunard Pond, and Birch Cove, and Lake Banook,' she said.
There are other water issues to be on the lookout for this summer.
'We test for enterococci in the saltwater and E. coli in freshwater,' said Nova Scotia Lifeguard Service Director Paul D'Eon. The service monitors provincial beaches.
'If we get poor results, we implement a closure and do re-testing,' D'Eon said.
If someone does come across blue-green algae in Halifax Regional Municipality, they should contact 311. Sightings at Nova Scotia beaches can be reported by calling 1-877-936-8576.

Brothers who gave $50K for palliative care room at nursing home learn tough lesson

Social Sharing The moment brothers Alan and Glenn von Weiler saw the palliative care room at their father's former nursing home — created in his memory — was one for the books, they say. "I think my dad would have been so happy," Glenn said. "My dad believed in giving back to the community. He did that all his life, and now he was able to do it posthumously." But just over a year after they saw the new palliative care room at the Fundy Nursing Home in Blacks Harbour, the brothers have a sour taste in their mouths. They learned from staff at the home that the room has been taken apart. In December 2022, Alan and Glenn's father, Joost, died after living at the home for a while. Shortly before his death, the brothers were so pleased with the care he had received from staff that they decided to make a $50,000 donation to the Fundy Nursing Home. The brothers, who live in Saint John, about 70 kilometres east of the home, spoke with the administrator at the time and ultimately decided on a palliative care room. The money would go into a trust set aside for the room. "It's life-changing for the families, so, you know, they deserve respect — they're not numbers, they're people," Alan said. The largest expenses for the project were the $15,000 in renovations that had to be done and the specialized palliative care bed, which cost about $15,300. Other features of the room included a pull-down, or Murphy bed, kitchenette items, and a heat pump. A shadowbox with their father's photo, a biography, and some of the paintings he did during his life were also added. WATCH | How much do a donor's wishes actually matter? Saint John brothers share cautionary donation story 3 hours ago Duration 3:26 On March 7, 2024, the palliative care room opened, with the von Weiler brothers in attendance. Not only did the room have everything a family could need for loved ones at the end of their lives, they said, but it also had a homey atmosphere that didn't come with regular rooms for residents. But recently, the von Weilers were informed by staff that the room had been disassembled — something the brothers never expected. "The enthusiasm from the staff was phenomenal," Alan said of the palliative care room. "How could I ever think that someone would go in and just take it apart?" The von Weilers wanted to get official confirmation of the dismantling, so they contacted Constance Gilman, the current administrator for the nursing home. In response, they received a letter, which they shared with CBC News. "I would like to apologize to your family about the misinformation that was shared with you, and would like to take the time to explain to you what the home plans to do to ensure that this important service is still in place and that your donation is not forgotten," Gillman wrote. She went on to say that the palliative care bed was being used for a non-palliative care resident because it was more comfortable for that person. "But the problem is, if you have someone coming up that needs a palliative care bed … that bed's not going to be available," Alan said. Because you can't remove a patient from a bed so another one can take the bed. He said the bed, with a special mattress to prevent bed sores, was specifically for palliative residents. Gilman's letter said that to avoid causing discomfort, the home didn't want to transfer a palliative care resident to the new bed. Brothers understand move She also said the palliative care room had been moved to another location with a wider doorway, so resident beds could be rolled into it. The room was now closer to the nursing desk to "minimize the risk" of a resident being "forgotten," she said. The brothers said the former administrator chose a location a little removed from the general traffic area to provide more privacy for families. But even so, Glenn said, he understands that patient health has to come first and moving the room was understandable, if it had the same fixtures as the previous one. Gilman's letter said the kitchenette items would be moved to the new space, but the Murphy bed was broken, so if families wanted to stay overnight, a sleeper chair could be rolled in. The art and the memoriam shadowbox would be put back as well, the letter said. After reading the letter, the von Weilers asked to see the new room. "It was basically an empty room with a recliner in it and a small little kitchenette," Glenn said. "If someone needed a palliative care room that day, it was not available. "I don't think that you should shut something down without opening up the new one." CBC News requested an interview with Gilman but did not receive a response. The von Weilers are still grateful for the care their father received while at the nursing home, but this experience makes them think they would have chosen a different location to donate to, had they known what was going to happen. They wonder if anything would have been different if they'd had a written contract outlining the request. The agreement with the home was a verbal one, aside from a receipt from the home that said, "Donation to memorial fund palliative care room." But legally speaking, there isn't anything that can be done in this situation, according to Toronto business lawyer Jonathan Kleiman. A promise to do something specific with the donated money could be enforceable, he said, but without a proper contract, it's a flippant promise. And even with a proper written agreement, Kleiman said, it's unlikely the contract would have specified a specific length of time that the room had to remain. "I find it very hard to believe that the nursing home meant to offer anything in perpetuity," Kleiman said. "So all the more reason to have something in writing, so you understand what you guys are getting, and there's no misunderstandings." The von Weilers believe this situation will make them more careful with future donations. They'll ask more questions and get things in writing. One of the most upsetting parts of the experience for the von Weilers was how they found out — from a staff member and not management. "I think it's just respect," Glenn said. "If you have people in the community investing in the community, I think that they deserve to know what's going on."

Nova Scotia Health works to speed up sepsis treatment

Nova Scotia Health is equipping front-line caregivers in some of the province's emergency rooms with potentially life-saving tools to treat sepsis. A team has been working to implement changes to enable a faster response when people present with sepsis symptoms. Sepsis is caused by the body's overreaction to an infection that is already present. Cases have been on the rise for the past few decades, according to Sepsis Canada. Recommendations from the health authority's own reviews into patient care are cited as factors for the changes. "Sepsis is a very real issue in our province," said Dr. Vanessa Sweet, the central zone sepsis team co-lead. "It was clear to us that we needed to take a different approach to it." The team examined the approaches of other health systems that have made progress in the area to then bring some of those ideas to the front lines of emergency care in Nova Scotia. One thing the group developed are sepsis treatment kits that include all the supplies needed to act fast. "And it has proven that way, I've seen these used many times, people are grabbing for them, instead of having to go pull things and getting pulled to different situations," said Terri McGregor, a registered nurse at Twin Oaks Memorial Hospital in Musquodoboit Harbour. Inside the ready-to-deploy boxes are blood-testing equipment, intravenous fluid supplies and tourniquets along with requisition forms and detailed instructions. Nurses now administer life-saving antibiotics Another key new care directive allows nurses to begin antibiotic treatment without approval from a physician. "If we had no physician on site, say, they're getting those antibiotics immediately," McGregor said. "This lets nurses work to their full scope of practice," said Sweet. Twin Oaks, Cobequid Community Health Centre in Lower Sackville and Hants Community Hospital in Windsor began implementing the changes in the first phase of the project. "Now over 90 per cent of patients at the three sites are receiving their antibiotics within the three-hour recommended time frame," Sweet said. "We've seen a drastic improvement in that," she said, adding the previous number was around 60 per cent. The program has since grown to include six hospitals, according to Nova Scotia Health. 'Every hour is absolutely essential' Detecting and treating sepsis early can be the difference between life and death, said the scientific co-chair of Sepsis Canada. "We know from the literature that every hour that someone is in severe sepsis and they're not getting appropriate treatment, their chance of dying goes up by 10 per cent," said Dr. Osama Loubani, who is also an emergency room physician in Halifax. "Every hour is absolutely essential." Karen Moxsom from Hardwood Lands in central Nova Scotia saw how fast sepsis can take hold when her husband got sick. A quality review of 74-year-old Gordon Moxsom's case was conducted after he died just over two years ago. At the time, his wife had not even heard of the condition. "There's not enough awareness out there for sepsis, it can happen so quickly. It's one of the top leading killers with cancer, with heart attacks," said Moxsom. "Nobody knows anything about it." She still maintains her husband may not have contracted sepsis had he not been discharged from the QEII Health Sciences Centre in Halifax with a catheter — where she thinks the infection started — following treatment of earlier heart problems. Included in the review is Moxsom's complaint that she did not receive proper guidance following her husband's discharge about how to monitor for infection, or any education about sepsis symptoms. She's still pushing for answers about his care and is encouraged to see there is further action to improve treatment. "I'm happy that they are doing it. I was glad to see that because I feel like I was a part of that by reporting what happened to Gordie." Moxsom now wants to see the changes implemented provincewide, which is something the action improvement team is now looking at as it attempts to scale up its work. The Halifax Infirmary is scheduled to start in the fall. A provincial rollout is planned after that.
