ABSTRACT

Spreadsheets are widely used software tools for data entry, storage, analysis, and visualization. Focusing on the data entry and storage aspects, this article offers practical recommendations for organizing spreadsheet data to reduce errors and ease later analyses. The basic principles are: be consistent, write dates like YYYY-MM-DD, do not leave any cells empty, put just one thing in a cell, organize the data as a single rectangle (with subjects as rows and variables as columns, and with a single header row), create a data dictionary, do not include calculations in the raw data files, do not use font color or highlighting as data, choose good names for things, make backups, use data validation to avoid data entry errors, and save the data in plain text files.

An interesting piece by @johnlauner.bsky.social in the @bmj.com recently. I know GP trainees who have done this too. Not all our younger doctors are leaving for Australia & NZ. Some are staying here but leaving the NHS. Somehow, the system has gone horribly wrong that this is happening. #MedSky
Botox, lifestyle medicine, and future general practice.

Some years ago I taught an exceptionally bright young
GP on a course. She seemed to grasp the values of the specialty intuitively.
I hadn't heard news of her for a while, but I discovered recently that she runs a private aesthetics clinic, offering botox, fillers, and so forth to people who want to look younger and are happy to pay for this.
Forgive me, but my heart sank. It wasn't the kind of career I'd hoped she might pursue.
At the same time, I recognised she may have made the choice for her own good.
We hear a lot about doctors emigrating, but I'm hearing of far more who stay in the UK but leave the NHS. Some are already thinking about it during their specialty training. I come across others when I do their appraisals two or three years later: they're carrying out sessions in aesthetics, lifestyle medicine, wellbeing clinics, or various screening services. Some are doing this part time to supplement their income or between spells of locum work, but a significant number are moving into full time private work. My perception is that these doctors include some of the best of their generation.
Their motives vary. These often include feeling overwhelmed by the punishing pace of NHS work. However, in some localities these doctors are finding the opposite: they can't make a living because different professions are taking over GP work, and practices are engaging far fewer sessional doctors. Many who do private work are parents who simply want to spend more time with their children.

Cancer Research UK today published a report which highlights changes in cancer survival rates over the last 50 years. Many headlines (like this one from the Guardian) have chosen to report the ‘doubling of cancer survival rates’ since the 1970s. But that's misleading... 1/18

There is a much stronger evidence base to support measles vaccination in all children and COVID vaccination during pregnancy, compared to annual COVID vaccination in healthy children. I think this is important distinction, and we should be cautious about mixing levels of evidence in discussions.
